Epicyclic gears obtain name from their earliest app, which was the modelling of the motions of the planets in the heavens. Believing the planets, as everything in the heavens, to be perfect, they could only travel in ideal circles, but their motions as seen from Earth cannot become reconciled with circular motion. At around 500 BC, the Greeks developed the idea of epicycles, of circles travelling on the circular orbits. With this theory Claudius Ptolemy in the Almagest in 148 AD could predict planetary orbital paths. The Antikythera Mechanism, circa 80 BC, experienced gearing which was able to approximate the moon’s elliptical route through the heavens, and actually to correct for the nine-yr precession of that route. (The Greeks could have seen it much less elliptical, but instead as epicyclic motion.)
EP, a versatile and multi-use answer, is not merely another simple planetary gearbox. EP high-tech planetary reducer is a genuine integrated concept, including countless functions combined jointly to provide a complete sub-assembly to the virtually all demanding machines.
EP is the best high-tech servo-reducer, specially focused on designs requiring:
Superior output torsional stiffness
Ultra-huge output radial stiffness and Tilting moment
Patented output bearing design
A high-tech planetary gear train, based on REDEX’s differential know-how
ISO 9409-1 productivity drive flange for installation pinions, pulleys, couplings, etc.
High input speeds
Superior acceleration and remarkable torque density
Minimum backlash (1 – 3 arc-minutes)
In-Line or proper angle arrangements
This versatile design helps it be possible for design engineers to find precise solutions to the most demanding applications.
Parallel shaft Gearmotors
The S Series style makes this gearmotor particularly effective for fan, pump and blower applications. To meet the needs of consumers in these sectors, the S Series can be available in the ft . or flange editions and can be completed with a wide variety of electric motors entirely produced by EP. Asynchronous motors both IEC and small (Planetary Reducer Gearbox B-BE-BX/M-ME-MX), servomotors (BMD) and reluctance motors (BSR) could be in conjunction with the S Series: with the breadth of its portfolio, EP provides customers with a superb balance of efficiency, expense effectiveness and dynamics.
The mixture of epicycle gear trains with a planet engaging both a sun gear and a ring gear is called a planetary gear train. In cases like this, the ring equipment is usually fixed and sunlight gear is driven.
